SEECIFICATION forming part of Letters Patent No. 682,560, dated September 10, 1901.

Application filed August 28, 189

To tu whom it irl/@ty concern,.-

Be it known that I, KORNEL MAsLoNKA, a subject of the Emperor of Austria-Hungary, residing at Neu-Sandec, in the Province of Galicia, in the Empire of Austria-Hungary,

have invented certain newfand useful Improvements in Seal or Controlling Looks; and I do hereby declare the following` to be a full, clear, and exact description of the invention, 1o such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention has relation to locks, more especially locks adapted for use on freightcars, and more particularly to seal-locks;

and it has for its object a lock the mechan-A zo ism of Which cannot be readily tampered with, while if used as a seal-lock the seal cannot be removed or destroyed by an attempt at removal.

The invention consists in structural features and combinations of cooperating e-lements, substantially as hereinafter described, and specifically pointed ont in the claims.

In the accompanying drawings, Figures 1 and 2 are fragmentary elevations of a door- 3o post and door of a railway-car, showing the locking-bar pivoted to the doorand the keeper in the door-post for the lock-bolt in Fig. 1 and the lock applied in Fig. 2; and Fig. 3 is a sectional plan View of Fig. 2. Fig. 4 is an outer face view of the lock with the key inserted and shown in section. Fig. 5 is a longitudinal vertical sectional View ot' the lock, the lock-bolt being shown partly drawn out of its casing and the gates that close the open end 4o of said casing thrown open. Fig. 6 is an elevation or outer face view of the lock with the main gate open. Fig. 7 is a detail sectional view of the device for locking the seal to the lock-casing. Fig. S is a cross-sectional view, and Fig. 9 a longitudinal vertical sectional view, of the lock, showing thelock-bolt locked to its casing. Figs. 10 and 12 are cross-sections of the internal casing, showing the locking-bolts gin their projected and retracted 5o positions, respectively, the tumblers for said bolts being removed in Fig. 12, Figs. 11 and '13 being fragmentary horizontal sections of Figs. 10 and 12, taken on a line above the tumblers. Fig. 14 is a crosssection of the internal casing, showing the safety lockingdogs q; and Fig. 16 is a fragmentary horizontal section of Fig. 14, showing one of said dogs in engagement with one of the bolts g. Fig. 15 is a View similar to Fig. 12, showing the impossibility of retracting both bolts g with a key having but one bit. Fig. 17 is a vertical section of the internal casing, illustrating the means for retracting the bolts h. Fig. 18 is a longitudinal Vertical section of Fig. 10. Figs. 19 and 22 are detail horizontal sectional views. Fig. 20 is a sectional. front elevation, and Fig. 21 av longitudinal vertical sectional view, of the lock adapted for use with leadseal-plngs; and Figs. 23 and 2l show the key in front and side elevations, respectively.

As shown in Figs. 1 to 3, the lock-bar d is pivoted at 3 to the car-door e, While the lockcasing b, provided with suitable bolt-flanges b', is bolted to the door-post,in which is formed a suitable recess d', acting as a keeper for the lock-bolt c. The lock-casing b is polygonal. in cross-section and provided in four of its inner faces with oppositely-arrangedrecesses, the recesses k in the two opposite walls serving as keepers for two reciprocally-movable spring-actuated sliding locking-bolts, and in the recesses t, which extend from end to end of the casing b in the other opposite walls, are arranged resilient keepers j on the outer free end of springs t', secured at the inner end in said recesses, said keepers having their proximate faces beveled andvbeing located near the outer endofvsaid casing,'which outer end is open and has in its inner end wall an opening o', as shown in Figs. 5 and 9, through which the lock-bolt c is projected when pushed into the casing to pass through one of the holes 1 or 2 in the lock-bar CZ When the latter is properly positioned and engage the keeper d in the door-post, as shown in Fig. 3.

To the lower horizontal edge of the casing,

central transverse ke 'hol at its open end, is hinged agate t, having a.

ett, and to the outerv Ioo face of said gate is pivoted a locking-dog n, whose drop when the gate is closed is limited by a stop-pin n', said dog adapted to engage a radial lug 8 on the key, Fig. 1. From the inner face of said gate t projects a perforated lug t (see Figs. 4 to 7) for purposes hereinafter described.

The lock-bolt c has an enlarged chambered hea'd f of the same form in cross-section as that of the casing b, the rectangular chamber therein being open at its outer end, from opposite side walls of which project flanges or ears 9, whereby the bolt can be seized and pushed into and drawn out of its casing. In the chamber of the bolt-head f is contained. the lock mechanism, and in the inner end wall of said chamber is formed a central recess fl, while two of its opposite side walls are slotted longitudinally, as shown at 10, Fig. 9.

Referring now more particularly to Figs. 8 to 18, it will be seen that the locking appliances are confined in a casing C, fitting the rectangular chamber in the bolt-head f, said casing being open at its outer end, which is closed by a plate 22, in which is formed a central keyhole 23, so as to register with the keyhole u in gate t when the latter is closed. The casing C has two chambers 2% and 25, in the outer one of which are conned the reciprocally and horizontally movable sliding bolts g, and in the adjacent chamber 25 are confined the reciprocally and vertically movable spring-actuated sliding bolts 7L, having their inner faces at the outer ends beveled or curved outwardly. (See Fig. 18.) As shown in said Fig. 18, the casing C has in rear of its chambers only side walls abutting against the inner end wall ofthe chamber in the bolthead f to hold said casing from being pushed too far into said chamber, and centrally of the rear wall of chamber 25 is a yoke 26, projecting beyond the rear edge of the side walls of casing C, Fig. 1S, into the recess f in the chamber in the bolt-head f, Fig. 9, to which yoke is secured the key-pin o,whose outer end projects into the keyhole 23 in front plate 22 of casing C, Figs. 8 and 18.

The form of the reciprocally-movable locking-bolts 71 is clearly shown in Figs. 17 and 1S. rlhey are mounted on screw-pins 27, having an attenuated portion passing through a hole in the heel of the bolts and carrying a spring 5, that keeps said bolts vnormally projected from their chamber. The form of the bolts g, which are not spring-actuated, is clearly shown in Figs. 12 and 15, and in cooperation with these bolts I use a tumbler or tumblers l, Fig. lO, which may have any suitable number and arrangement of wards.

As an additional means of safety-namely, to prevent the bolts g from being retracted into the casing one after another by means of a key having a singley bit only, Fig. 15-1 provide two locking dogs or latches q, Figs. 11 to 16 and 19, held against the bolt by springs 11, Fig. 14, said bolts having an inclined face 12 on one side of an approximately central enlargement or bearing and a lockshoulder 13 on the opposite side thereof, Fig. 19, so that when both bolts g are simultaneously retracted by means of a key having two bits 4, Figs. 23 and 24, the inclined or beveled faces 12 will ride over the latches q and force the same against the walls of casing C, thus allowing both bolts to slide inwardly over said latches. If, on the contrary, an attempt is made to retract one bolt after another by means of a key having but one bit, the retraction of the upper bolt, ior instance, Fig. 15, would force the upper end of the right-hand latch against the casing-wall and tilt the lower end of said latch inwardly into engagement with the lock-shoulder 13 on the lower bolt g, thus preventing its retraction by the further turning of the key, as will be readily understood, a similar operation t-aking place if the lower bolt g were first retracted. Then the left-hand latch q would come into operation and lock the upper bolt. The spring-bolts 7i, which project into the longitudinal slots 10 in two of'the opposite sides of the headfof lock-bolt c, are not directly retracted by the key, Figs. 23 and 24, but by means of a sleeve m, mounted on the key-pin and held in normal position by means of a spring p, coiled upon said pin and bearing on the sleeve and on the yoke 26, Fig. 1S, said sleeve having two radial bits 6, adapted to engage suitable notches in the said bolts 7L, Fig. 17, and is provided on its front face with an incline forming a shoulder 7. The key, Figs. 23 and 24E, has, besides the two bits et, two radial lugs 8, hereinbefore referred to, and when a lead plug-seal is used I provide an outer gate 18, Figs. 3, 4f, 5, and 7, hinged to the upper rear edge ot' the casing, said gate being held in a closed position when the lock-bolt cf is fully pushed into its casingi. e., in its locked positionw-by means of a latch 19, Figs. 3 and 4, pivoted to one of the lateral iianges 9 of the bolt-head and held in position by a pin projecting from the outer face of said gate. (See Figs. and 4.)

When the lock is used as a seal-lock with paper or cardboard seals, the outer end of the headfof the bolt c is provided with a sealchamber s, open at its outer end, and in its opposite end wall 2S is formed an opening 15 and a keyhole w, through which the key-pin 0 projects, and between said wall 2S and the outer end plate 22 of casing C, containing the locking-bolts, is arranged a sliding locking bolt w, consisting of a block having a locking-pin 17, which when the bolt-headfis fully pushed in traverses the aforesaid opening 15. The locking-bolt wis normally held projected from the lock-bolt head f by a spring 16, Fig. 6, one end of which engages the said block of said bolt, said spring being coiled on a pin 16', and its other end has bearing on a pin 16", both pins being preferably secured to plate 22 of casing C, Fig. 8.

It will be observed, and as more clearly IOO shown in Fig. 5, that the lock-bolt c f cannot be entirely withdrawnfrom its casing b, as it is obvious that said bolt can move ont of its casing only a distance equal to the length of the slots in its opposite sides, the inner end 10 of said slots acting,'together with the keepers .7', as stops. If the lock-bolt c f is drawn out of its casing to the full extent, the spring-actuated locking-bolts h will be projected from the bolt-head f by the action of their springs 5, and so will the locking-bolt w. When the lock-bolt c f is in the position last referred to, a cardboard seal is placed in chamber s at the outer end of the bolt-head]E and the gate t closed, and the lugv on the inner face thereof will be forced through the seal or thro ugh an opening previously made therein into the opening in the chamber-wall. If now the bolt is pushed into its casing, the locking-bolts h will be forced inwardly into the bolt-head f, their inner or rear faces being curved to admit of this, as hereinbefore stated, and as the bolt-headf is about to be fully pushed in the locking-bolt w is likewise pushed inwardly, its locking-pin 17 passing through the perforation of the lugo on gate t, thus locking both gate and seal to the boltheadf. At the same time the locking-bolts h are brought in line with their keepers lo and are projected into the same by their springs 5, while the sliding bolts g, previously projected into the slots 10 by means of the key, snap over their resilient keepers j, as shown in Fig. 9, thus locking the bolt-head f to four sides of its casin g. Of course it will be readily understood that when the bolt-head is movedout of its casing b sufciently for the locking-bolt w to clear the end of said casing, Fig. 5, the spring 16 of said bolt zu will throw the same out and automatically release the seal and gate if.

When paper or cardboard seals are used, I preferably dispense with the gate 18 and provide the gate t with segmental sight-openings 30, Figs. 4and 6. When a lead seal Z is used, the perforated lug o on gate t is dispensed with, as well as the keyhole and sight-openings therein, but has simply a slot a; in line with the aforementioned aperture 15 in the back of seal-chamber s for the insertion of the perforated shank y ot' the seal Z into the path of the` locking-bolt w, so that the seal Z acts as a means for locking gate t to bolt-head f, and said gate can therefore not be opened without iirst cutting away the enlarged head of said seal Z. This arrangement is clearly shown in Figs. 2O to 22, and in this construction the lockingdog fn, hereinbefore referred to, is pivoted in the sealchamber s.

In throwing out the locking-bolts g by means of the key the latter is turned in the direction of the hands of a watch, and in order that this may be effected the sleeve m is mounted on key-pin o, so as 'to have endwise motion thereon, as hereinbefore described. As one of the bits 4 of the'key slides on the inclined or cam face that forms the shoulder 7 on the outer face of sleeve m the latter is forced inwardly against the stress of its spring p until said bit has cleared the said shoulder 7, when-the latter is thrown forward again to a normal position by its said spring p.

To open the lock, the key is inserted and turned in the direction of arrow, Figs. IO and 12, whereby the bits 4 on said key lift the tumblers, release the bolts g, and retract the latter into the bolt-head f, the tumblers under the stress of their springs rengaging the bolts in a well-known manner. As soon as bolts g are retracted one of the bits 4 engages shoulder 7 on the outer end of sleeve m, Fig. 12, and on the key being further turned sleeve n is also turned, its bits 6 engaging suitable notches in the bolts h, Fig. 17, and retracting the same against the stress of their springs. The key can then be locked against rotation in a reverse direction under the action of the` springs 5 of the bolts h by means of the latch n, as hereinbefore described.
